<p><P>PROBLEM TO BE SOLVED: To provide an information-processing device which accurately determines a display object on a display part which an operator indicates by his (or her) touching operation even if his (or her) viewpoint moves to cause motion parallax. <P>SOLUTION: The information-processing device includes: a first conversion part 13 which uses positional information in a world coordinates system on a touch position-detecting part 6, which detects an operator's touch position, to compute a touch position on the world coordinates system from the operator's touch position; a semilinear line information-generating part 14 which generates information on a semilinear line which connects the position in the world coordinate system of the operator's viewpoint to the touch position in the world coordinate system; a first determination part 15 which uses positional information in the world coordinate system on a display part displaying a display object, which the operator visually recognizes via the touch position-detecting part, to determine whether the semilinear line crosses the display part; and a second determination part 16 which uses the positional information in the world coordinate system on the display object to determine whether the semilinear line crosses the display object displayed on the display part which is determined to cross the semilinear line. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
